Kingdom of Gwent

The Kingdom of Gwent was a medieval Welsh kingdom that existed from the 5th century to 942 and from 974 to 1063, with Caerwent and Porth-is-Coed serving as its historic capitals. Gwent was established after the fall of the Roman Empire, and it was conquered by Gruffydd ap Llywelyn in 942. It regained its independence upon Gruffydd's death in 1063, but it was overrun following the Norman conquest of Wales.
